BF during the test led to lower maternal 2 h post-load glucose and insulin levels compared without BF, adjusting for covariates, including age, ethnicity, parity, GDM severity, the amount of formula per 24 h, frequency of feedings per day, and the duration of fasting, while basal insulin and glycemia, as well as insulin resistance indices, were not significantly influenced [64]. Here, INS is linked to gestational diabetes.
